Bioremediation can be defined as any process that uses microorganisms or their enzymes to remove and or neutralize contaminants within the environment (i.e., within soil and water) to their original condition. Bioremediation can be employed to remediate specific types of contaminants such as; petroleum hydrocarbons, polycyclic aromatic hydrocarbons (PAH), polychlorinated biphenyl’s (PCB), chlor...

The present work deals with the bioremediation of a sediment sample contaminated by heavy metals, collected in the Ancona harbour, Italian Adriatic Sea, Mediterranean Sea. Bioleaching of the sediment was performed with a mixed culture of acidophilic, chemi-autotrophic Fe/S oxidising bacteria, in the presence of elemental sulphur as substrate. Such element resulted to be fundamental both for cel...

The present study deals with the assessment of toxicity of distillery effluent on soil microorganisms and its quality improvement through bioremediation using Pseudomonas spp. Under lab scale experiment, different dilutions of distillery effluent i.e. 25%, 50%, 75% were used to examine effects on physico-chemical parameters of effluent and on soil microflora e.g. algae, bacteria, fungi and acti...

The term bioremediation has been introduced to describe the process of using biological agents to remove toxic waste from environment. Bioremediation is the most effective management tool to manage the polluted environment and recover contaminated soil. The hazardous wastes generated from the chemical processes/operations are being treated using physico-chemical and biological methods by the re...

The remediation of contaminated soils is one of the major environmental problems in industrial countries today. Among the different techniques that can be applied, in situ bioremediation, which relies upon the use of indigeneous microorganisms to degrade the contaminant, is one of the most attractive, both from an environmental and an economic viewpoint. A full-scale bioremediation process requ...

A fundamental long-term issue confronting sediment bioremediation is the lack of understanding of contaminant-sediment interactions and the impacts of such interactions on the failure to achieve treatment goals [1]. Little is known about the mechanisms of PAH and other hydrophobic organic compound sequestration and aging in sediments and the resulting effect on chemical and biological availabil...

When investigating the treatment of contaminated soils, the application of biotreatment is growing rapidly. Factors influencing this rapid growth include that the bioremediation processes are cost-efficient, safe, and nature-based. In the past, thermal, chemical, and physical treatment methods have failed to eliminate the pollution problem because those methods only shift the pollution to a new...

In this report, morphology and fiber diameter differences of electrospun polysulfone (PSU) fibers on bacterial immobilization and bioremediation performance were evaluated. PSU fibers were produced with aligned or randomly oriented morphologies, and PSU fibers with thinner and thicker diameters were also produced. PSU fibers were utilized as carrier matrices for bacterial integration and the sa...
